CAN-SOLDERING MACHINE.

SPECIFICATIONforming part of Letters Patent No. 359,723, dated Edam-ch22, 1887.

Application filed June 2S, 1886.

To (LZZ whom it only concern.-

Be it known that I, Tnonns H. HAMILTON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Can-Soldering Machines 5 and I do declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the lcttors and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in can-soldcriug machines, as illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the machine with the rotary carrier and its support in section. Fig. 2 is an enlarged side detail view of the soltlerin'g-copper and its supportingframe. Fig. 3 is a top detail view of Fig. 2. Fig. 4. is a section of the rotary carrier with the soldcringcoppers removed. Fig. 5 is an enlarged side detail view of the can-holder,

showing the coppers in position when soldering.

Similar letters refer to similar parts throughout the several views.

The letter A designates the frame or table support, which is formed with a circular recess, c, in which the hub Z) of the carrier B neatly tits, and thereby forms a bearing for the same.

The shaft 0 has its lower bearing at a,with its upper one formed in the girder c overhead. Between the bearings of the shaft is arranged the gear-wheel d, which communicates with and drives the pinions d, attached to and which move with the carrier B.

The shaft 0 is driven from the counter-shaft E by means of the pinions c e,and the countershaft driven by the pulley c, placed thereon. The counter-shaft is supported on the bearings e", secured to the girder c. The carrier 13 rotates in a horizontal plane, and is supported on the frame A in such a manner that it can be readily rotated by the operator taking hold of the handle I) and moving it as desired. On

the carrier is arranged the can-holding device D, which consists of two disks, f, attached to the spindles f ,which rotate freely in the bear- Serial NoltldS-li).

ingsf, secured to the carrier 13. One of the spindles has an endwise movement by which the cans are placed between the disk, and is held against the can by means of the spring f and the collarsf. The opposite spindle is provided with the pulley g, over which passes the belt 5/, which consists of any flexible material or chain that communicates motion th era to from the pulley Zseeurcd to the spindle 71.

The spindle h carries the pinions d, which com inunicate with the gear-wheel (I, thus contiir ually rotating the cans when placed between the disks f, thereby keeping the cans continually rotating, that the solder maybe distributed 6 equally around the seams when it is in a molten condition, and likewise permitting it to cool before the rotation of the can is stopped by its removal from between the disks.

The soldering-coppers Fare formed at their lower ends to suit the curvature of the can and the flange of the ends, and they are supported by the rods h, secured to the yoke h" by passing through the bearings thereof. The rods are held in their proper position in relation to moving a can from thereunder, by means of the cord 2",passing up over the pulleys Z to the treadle M, which is depressed when the coppers are to be raised.

To the front partof the coppers F are arranged the solder-guides a, which are .open at 0 both ends, and which direct the solder to the proper place on the cans when placed therein.

The coppersF are heated by the flame from the burners G. The said burners may be hydrocarbon self generating burners supplied 5 with oil, the ordinary Bunsen burner, or any suitable kind, and they are placed to deliver their flame against the coppers, thereby continually keeping them subjected to the flame,

and thus acquiring sufficient heatto continu- 10o ally operate the machine.

By the construction herein shown and speci- The yokes h are sup- 8c tied the cans are placed horizontally on the carrier, and both ends of the said can are in a position to be operated on at once and brought in position in relation to the coppers by the movement of the carrier. The cans continually rotate on the carrier, properly distributing the solder around the can and prevent it from settling at one place in excesses the cans are rotated until. the solder cools, thus resulting in a superior work and facilitating the manufacture.

It is obvious that the can-holders could be set at right angles, or in other positions than that shown, and accomplish the same result, and therefore I include in my claim any such variation.

In operating the machine, the cans with their ends unsoldered are placed between the disks fby a helper, at the position designated by 20 the numeral 3, and the carrier is rotated snffieiently to place the can under the Coppers, which the operator has previously raised. The coppers are then lowered and brought in contact with the ends ofthe rotating can, which are sufficiently heated thereby, and the solder applied, by the operator either dropping a piece in the guide n or feeding sulticientwiresolder therein against the hot can, which is distributed around the can by its rotation and sweated in between the seams by the coppers, after which the coppers are raised by de pressing the treadle, and the carrier is again sufficiently moved by the operator to place an.- other can under the eoppers, and so on. The

soldered can in the meantime continually rotates until cooled, for the purpose set forth, and is finally released from the disks at the position it was placed by the helper.

Having described my invention, what I claim, and wish to secure by United States Letters Patentyis- 1. In a can-solderingmachine, the combi nation of the carrier B, rotating ina horizontal plane, the can-holders I), mounted on the earrier,with their axis of rotation always ina horizontal plane, and mechanism, substantially as described,to continually rotate the said can-holders, for the purpose specified.

2. In a can-solderingmachine, the combination of the rotary carrier 13, moving in a horizontal plane, the can-ho1ding devices D, mounted on the earrier,with theiraxis of rotation in a plane parallel with thatin which the carrier moves, and mechanism to rotate the can-holding devices while and after the cans are being soldered.

3. In a cansoldering machine, the combination of the carrier B, can-h ol ding devices D, mounted on the carrier, the soldering-coppers F, the rod h, to be adjustediinrelation to the yoke In, the yoke hiandthe eross'rod 7s, forming a pivot, as set forth.

4. In a cansolderingmachine, the combination of the solderingcoppers F, the solderguides at, the rod h, to be adjusted in relation to the yoke 7L2, the yokelfl. and the cross-rod 'c, forming a pivot, as set forth.

5. In a can-soldering machine, the combination of the soldering-eoppers F, the rod h,

to be adjusted in relation to the yoke If, the

yoke h, and the cross-rod is, forming a pivot, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
